Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy and hydropower engineering construction, and particularly relates to an inclined shaft advanced pipe shed structure. Background Art

[0002] At present, during the construction of inclined shafts in soft rock fracture zones, the advanced support measures will directly affect the project safety. The conventional advanced pipe shed only has a main steel pipe structure, which is prone to pipe shed deformation under the geological conditions of soft rock fracture zones, and cannot play the role of the pipe shed support framework, affecting the construction safety of inclined shafts in soft rock fracture zones. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a pipe shed support structure with simple structure, convenient manufacturing, and capable of effectively improving the structural strength of the inclined shaft advanced pipe shed.

[0004] The technical solution of the utility model is as follows: an inclined shaft advanced pipe shed structure, comprising: seamless steel perforated pipes, steel bars, and grouting steel pipes. A plurality of the seamless steel perforated pipes are connected side by side to form a pipe shed structure. The length of the seamless steel perforated pipes is the same as the length of the pipe shed. A plurality of the steel bars are arranged at intervals on the outer wall of the grouting steel pipe and fixedly connected to the grouting steel pipe. The intervals between the plurality of steel bars are the same. The steel bars and the grouting steel pipe are located inside the seamless steel perforated pipes.

[0005] Further, the number of the steel bars is 3.

[0006] The beneficial effect of the utility model: An inclined shaft advanced pipe shed structure of the utility model strengthens the pipe shed support capacity, reduces the risk of pipe shed deformation, is convenient for manufacturing and use, and improves the pipe shed construction efficiency by arranging a plurality of steel bars at intervals on the outer wall of the grouting steel pipe and fixedly connecting them to the grouting steel pipe, placing the steel bars and the grouting steel pipe inside the seamless steel perforated pipes, and finally connecting a plurality of the seamless steel perforated pipes side by side to form a pipe shed structure. Brief Description of the Drawings

[0007] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the following drawings are only some embodiments of the utility model. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0008] Figure 1 is a structural schematic diagram of an inclined shaft advanced pipe shed structure of the utility model.

[0009] Figure 2 is a use state diagram of an inclined shaft advanced pipe shed structure of the utility model.

[0010] In the figure: 1 - seamless steel perforated pipe, 2 - steel bar, 3 - grouting steel pipe. Specific embodiments

[0011] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and defined, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0012] As Figure 1-2 shown, an inclined shaft advanced pipe shed structure includes: seamless steel perforated pipes 1, steel bars 2, and grouting steel pipes 3. A plurality of the seamless steel perforated pipes 1 are connected side by side to form a pipe shed structure. The length of the seamless steel perforated pipe 1 is the same as the length of the pipe shed. A plurality of the steel bars 2 are arranged at intervals on the outer wall of the grouting steel pipe 3 and are fixedly connected to the grouting steel pipe 3. The intervals between the plurality of steel bars 2 are the same. The steel bars 2 and the grouting steel pipe 3 are located inside the seamless steel perforated pipe 1.

[0013] Preferably, the number of the steel bars 2 is 3.

[0014] During use, use a geological drill to follow the pipe and drill to the designed hole depth, weld 3 steel bars 2 (C25 steel bars) and 1 grouting steel pipe 3 (Φ32×3.5mm, Q235B seamless steel pipe) that match the length of the pipe shed into a whole, and then insert them into the seamless steel perforated pipe 1.

[0015] The above has described the embodiments of the present invention in detail with reference to the drawings, but the present invention is not limited to the above embodiments. Those skilled in the art can make various changes within the scope of their knowledge.
